I'll also note that from a previous comment ( https://news.ycombinator.com/item?id=33055240 ) you claim to be a PhD student and the questions you are asking may be deeper than the regular freshman calculus question and thus held to a higher standard (expecting use of the proper terms, and using MathJax / LaTeX for more complicated formulas).
Stack exchange in general, as a Q&A site is optimized for being a Q&A site which means that it traded off some of the ability for it to be a general discussion site and questions that need a back and forth explanation session tend to fit poorly within that framework.
If your question is one that needs that back and forth, you may find it better to schedule some time with a professor or grad student in the math department who can provide that denser communication channel and provide real time feedback on the proper terminology.
